Hello everybody...
i would like to know the correct procedure to calculate
heat load..
i would like to know how heat load and cooling estimations are done for malls & multiplexes..
can anybody help me in this regard?

in my world, i dont do it.......i pay my consulting engineer to do this. I give him a bais of design, building type, envelope etc, he gives me a quote for his design fee, that is included in design build price. if plan and spec, this is already done.

kapk20: your answer is spelled: P R O F E S S I O N A L M E C H A N I C A L E N G I N E E R. There are guidelines that exist when looking at spaces such as what you are referring to. Not only from a load standpoint (heating and cooling requirements) but also for infiltration and outside air. Consult a professional. All the best, John.

Everyone has a purpose in life..........even if it's to be a bad example.

You need to obtain and learn the material and process in ACCA's Manual N. Manual J is for residential and Manual N is for commercial.

Be prepared to spend time in study and practice. You must be patient and willing to put in the study time with either or both of these manuals. Manuals J & N are the industry stardards for performing load calculations.

Originally posted by bdclark And remember Manual J and Manual N both leave some leeway...there have been instances where guys have used 75-85% of the manuals'"calculations" and have been very accurate and effecient with their "calculations."

My recommendation is to do a search for load estimating programs. There are a lot out there so you have to be careful. Some are free and some are not. They all take time to learn, and you have to be careful with the results. Good luck!
